(rennin a .1. q ,,3', u nes remains at it lndiana have invented new and uscii' improvements in lllmergency tJto-ps l'cr supported by a water snpi 1 having: a plug value which lQl'tHGllllS the escape oi? water the valve beina eutometicad released when its 1 n means is suhected to heat. llc oJuen happens that one or more oi these ralres are automatically unseatcd and the water continues to flow l 11 said heads until the supply is cut oil. l4. the spriuldinp; system in a place remote from the main wa er valve the water supply canno he out off soon enough to prevent clainae e to the stock or merchandise in the room by water.

lit is therefore the purpose oi? this invention to provide a devi e which can be quickly and conreuiently associated with each sprinlclinni head to stop the dew ol" water hin a tow seconds.

n 'eaiiryingr out the invention, it is purn'os to iirovioe a suhstentially wed shaped element desinned to be inserted within the sprinhlinp; head and subsequently driven therethrour h an appreciable dis tance to cause the said elements to etlectively close the water outlet opening of said head the invention resid n in the construction... combination and arrangement o parts as claimed.

The device forming the subject matter of invention comprises h ndle 10 which 'erahly consists oil an el gated piece of wood. wait-h mar vary in size without departing from the spirit of the invention. Secured to this handle adjacent one end are spaced. ll-shaped elements 11 which. are arranr; i to straddle the handle and having their cross pieces spaced from the upper suri ace thereoi to re cite the support for the wcdee shaped nher above referred to. .lllso secured to the upper side of the handle is a strip oli resilier ma ial indicated at 12. one end oi which is otlisetat to be received by the tn heino' spaced Til the oitlset eXtremthe handle as shown in Figure l. inasmuch l the weeoye shaped in mber is adapted to be positioned between this effect extremity 13 off the strip 12 and the handle .0 as shown in l 'rure l. The strip used to in hcldin the wed support 14: properly associated with the hand e tor i The wedge shq esl m mber is indicated at 15, and mounted on its support 142, and held positioned th on h 'led tasteni elements 'lie are preferably two oil such rasten ncf elements hree ded into the support 141., the e enents heinp; passed through a longitudinal slot l7 so that the wedge Slllpflfil membe can he moved longtitudinally of its support in a manner and for a purpose to be nr .entl described. ranged ahoye and secured to the wedeje sh aped member is a metallic hand 18 to protect the member from wear by contact with the sprinkling hes d the wedge shaped memher heino; preierahlv constru 'ted oi wood Secured to the underside of the support 14; is a leno th 0t ruhber or other relatively soft material indicated at 19 which serves as a ,a'aslret to malte a fluid tiaht onnection between the said support and the water outlet opening)? oi the sprinkling; head when the wede e shaped mcmher is arranrred in position tor use. The wedge shaped member is desiened to receive a metallic plate 1.5 which is also slotted to accommodate the fastening element 16 the heads oi? the his teninn elements reposina' on this plate to permit the wedge shaped member to slide treelv as will he readily understood.

brackets 20, each of which is formed with an opening 21 as shown in Figure 6, and slidable through these brackets is a ram rod 22 which is preferably provided with a stop pin 23 to limit the movement of the rod in one direction. This rod is utilized to drive the wedge shaped member through the sprinkling head 24 after the said member has been positioned within the head as shown in Figure 1.

In practice, assuming that the valve of the sprinkling head has been removed therefrom, and it is desired to stop the flow of Water through said head, it is only necessary to arrange the support 14 of the wedge shaped member 15 within the clamps 11 carried by the handle 10. After the parts have been thus associated, the wedge shaped member is slipped within the sprinkling member 24 as shown in Figure'l, and the ram rod 22 subsequently reciprocated to strike the end of the wedge shaped member 1.5, and thus wedge this member within the opening of the sprinkling head. As the member 15 is wedged within said head the gasket 19 is compressed against the head directly above the water outlet opening thereof, and seals or closes this opening to out off the flow of water. The wedge shaped member remains in this position until the main water supply valve of the water system can be closed, after which the wedge shaped member can be moved from the sprinkling head, and the latter then supplied with another valve. After the wedge shaped member has been driven into the sprinkling head, the handle 10 can be removed therefrom, and subsequently used in conjunction with another wedge shaped member if the circumstance should require its use.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

lVhat I claim is:

1. A device of the character described. comprising a handle, inverted Ushaped members secured to the handle and having their intermediate portions spaced therefrom, a wedge shaped member, a support therefore, said support reposing upon the handle and received by the U-shaped members, resilient means interposed betn-een the support and said intermediate portions of the U-shaped members to assist in holding the support fixed with relation to said han dle, said wedge shaped member being capable of sliding movement on said support, and rod slidably mounted on the handle and adapted to move the wedge shaped member in one direction on its support for the purpose specified.

2. A device of the character described comprising a handle. a wedge shaped member, a support therefore including an elon gated member reposing upon the handle and. projecting beyond one end thereof. means for clamping the support to the handle. said wedge shaped member being longitudinally slotted, headed elements passed through said slot and secured to the support for associating the wedge shaped member with the support for sliding movement thereon, yieldable material secured to the underside of that portion of the support which pro jects beyond the handle a metallic member covering the slot of the wedge shaped member. and a ram rod slidably mounted on the handle and adapted to be moved into engagement with the wedge shaped member for sliding the latter in one direction on its support for the purpose specified.

In testimony whereof I at'fix' my signature.
